Much like a miniature radio station, the transmitter broadcasts over an FM radio signal. The receivers are used to pick up the broadcast up to 150 feet away. The system helps large or small groups overcome background noise and distance to clearly hear the tour guide. The system is composed of a PPA T46 Transmitter, microphone, and optional PPA R37 or R35-8 Receivers equipped with headphones, earphones, or neckloops. To avoid difficulties, please read through these instructions, and keep them for reference. If you have problems, don’t hesitate to call Williams Sound customer service at 1-800-843-3544. FCC Regulation FCC regulations, section 15.21, requires the user to comply with the rules of transmitter operation. Any changes or modifications not expressly approved for compliance may result in the loss of all privileges and authority to operate this equipment.
